1. Verify your Fuel Level

An empty gasoline tank is one of the most frequent causes of lawnmowers not starting. Before attempting to start your mower, be sure that there is enough petrol in the tank.

2. Examine your Fuel Filter

The mower might not start if the fuel filter becomes clogged because it will restrict fuel from getting to the engine. Identify the gasoline filter and inspect it for obstructions. If so, clean it or swap it out as needed.

3. Inspect The Ignition Plug

Your lawn mower may be difficult to start if the ignition process is hampered by a bad spark plug. Check the spark plug for wear or damage after removing it. Replace or clean the spark plug as necessary.

4. Verify Your Air Filter

The combustion process may be hampered by a filthy or clogged air filter that restricts airflow to the engine. If the air filter is dirty, take it out and clean or replace it.

5. Look Over The Carburetor

When combining fuel and air for combustion, the carburetor is an essential component. The engine may not start if the carburetor is clogged or broken. If necessary, clean or fix the carburetor to ensure proper operation.

6. Check the Security Features

Many lawnmowers have safety measures like a dead man's switch or a lever to control the blade. The mower won't start unless these safety features are properly activated.
